Abstract: According to an aspect of this disclosure, a circuit includes a voltage source and an output load, first and second resonant modules disposed between the voltage source and the output load, and first and second transformers. The circuit is further arranged such that the first transformer is disposed between the first resonant module and the output load, and the second transformer is disposed between the second resonant module and the output load. The circuit also includes a plurality of half-bridges coupled between the first and second resonant modules and the voltage source. The circuit further includes a voltage divider disposed between the voltage source and the plurality of half-bridges.

Abstract: According to one aspect of the present disclosure, a single-stage converter includes a rectifying circuit and a buck-boost circuit. The buck-boost circuit includes an inductor with a center tap configured to supply an output of the buck-boost circuit to the rectifying circuit. The buck-boost circuit also includes first and second interleaved arms arranged in parallel with a voltage input of the single-stage converter. The first and second interleaved arms are each coupled to the inductor and include a plurality of switches operable to control the output of the buck-boost circuit.
